Tian Di Yuan Su: Scatter Count Buys Picks Rather Than Prizes

The free games in this elemental slot begin at eight spins with doubled prizes as standard, and that starting point is the same regardless of how the round was triggered. What the scatter count changes is the number of bonus picks: three, four or five Moon Spirit scatters award two, three or four picks respectively.

Inserting a pick stage between the trigger and the reward means the scatter count improves your expected outcome without settling it. Each pick can add more free games or push a multiplier higher, and since the two reward types are distinct, a player with four picks could receive four of one kind and none of the other.

The totals the picks can reach are substantial. The round is capable of climbing to thirty-three free games at a 15x multiplier, which is more than four times the base allocation at more than seven times the base rate. That is a very wide range for a feature that always opens identically.

Further Moon Spirit scatters landing during the round add another fifteen spins on top, which is a generous retrigger compared with the eight-spin starting allocation.

A Sun Spirit Wild doubles any win it takes part in and substitutes for everything except the Moon Spirit scatter across the thirty paylines. That doubling operates in base play as well as during the round, so it presumably compounds with whatever multiplier the picks produced.

The naming is worth noting for its symmetry: the Sun Spirit drives wins, the Moon Spirit drives the bonus, and the two never substitute for each other.

No confirmed volatility rating is listed. The pick-based scaling means results vary depending on how generous the picks turn out to be, which places a second layer of chance after an already uncertain trigger.

The listed top award of 50,000 times your bet per line puts this among the more rewarding titles built around a single scatter feature.

Tian Di Yuan Su suits players comfortable with a bonus whose parameters are decided in stages rather than at the trigger, and who understand that five scatters buys four attempts at improvement rather than a guaranteed better round. Anyone expecting a heavier trigger to award more spins directly will find the game routes that benefit through the pick screen instead.
